Ok, I admit this is not a tip, but information I found out today and could not find anywhere in documentation.
I am upgrading one of my longer running customers to NAV2015 (eventually). So one of the tasks is to make pages for these creative forms with many fields.
I thought to be smart and save some real estate by promoting a fast tab with a lot of flags. I had 8 flags, so I expected a fasttab with 8 occurances of Yes or No.
Instead, there are only 5 promoted fields. (Nee means No in Dutch).
So I started experimenting, searching on internet and testing in 2015, since I am making the pages in 2009R2 for a hybrid phase.
It seems that there is a limit of promoted fields on fasttabs to 5. Don’t ask me why. Must be something someone thought make sense as a decision for the entire NAV community.
So, Microsoft: Please remove this limitation, or at least make it like 10 or so.
